Operating Systems
Muhtasari
Every time you tap an icon, type a command or simply ask a smart speaker a question, you are talking to an operating system. It is the software working quietly in the background that manages the hardware, runs your programs, handles errors and keeps the whole machine secure. Without it, a computer would be almost impossible for an ordinary person to use.
In this lesson you will learn what an operating system does and, in particular, the four ways it can let a human communicate with a computer: the command line interface, the graphical user interface, and the newer dialogue-based and gesture-based interfaces. You will compare their strengths and weaknesses and learn to match the right interface to the right user, exactly the kind of judgement ICT exams reward.
